Title: |
INTERACTIVE GUI INTERFACE FOR AUDIO TRANSFORMATION |
|
Pre-Requisites: |
INTEREST IN AUDIO PROCESSING, VERY GOOD C++ PROGRAMMING /GUI PROGRAMMING SKILLS. |
|
Description: |
This project will implement a C++ GUI interface for audio processing classes in the Sound Object Library, a C++, OO library of audio processing tools. It also requires programming of audio manipulation classes. The main manipulationm class will be a spatial warping routing which will modify/warp image representations (.JPG, .TIF, .BMP, ETC) of sound. The warping routine will involve matrix manipulation and programming in C++. The image representation of sound will be a 2-D spectrogram/time-frequency distribution. The warped distribution will then be transformed back to a sound reproduced in real time as a .wav file. |
|
Language(s): |
C++ Visual Studio |

Title: |
HIGH RESOLUTION ANALYSIS AND SYNTHESIS OF SOUND IN THE SOUND OBJECT LIBRARY. |
|
Pre-Requisites: |
INTEREST IN AUDIO PROCESSING, VERY GOOD C++ OO PROGRAMMING SKILLS. |
|
Description: |
This project will implement the analysis and synthesis of sound. This will involve the development of C++ classes for audio processing in the Sound Object Library, a C++, OO library of audio processing tools. Classes will be designed which represent sound as a 2-D time-frequency distribution (the Wigner Distribution / Modal Distribution) and classes which implement real-time sound synthesis from analysis data. Synthesised sounds will be compared with other synthesis methods from spectrograms. |
|
Language(s): |
C++ Visual Studio |
